TCR Advanced undertakes Mechanical Testing, Chemical Analysis, Positive Material Identification, Failure Analysis, Metallography, Corrosion Testing, Non Destructive Testing and Third party Inspection Services.
The following sample requirements will provide optimal sample size for our engineers to conduct the required tests. If your sample size does not meet the requirements listed below, please contact TCR Advanced because subsized samples can be used or we may have other methods for conducting similar analysis. Sample sizes larger than those listed will not present a problem, but additional machining may be required. The table below is considered as a good reference point for most samples. For special items or if limited amount of material available, please contact TCR Advanced.
TYPE OF TESTING SHEET* PLATE* ANGLE BAR PIPE TUBING
Chemical** 2" X 2" 2" X 2" 2" long 2" long 2" long 2" long
Tensile 2"W X 12"L Note (1) 18" long 6" long/Note (2) Note (3) 12" long
Flattening ---- ---- ---- ---- 3" full ring 3" full ring

Hardness 2" X 2" 2" X 2" 2" X 2" 2" long 2" long 2" long

Note :

  1. Plate up to ¾" thick requires 2"W X 18"L; Plate greater than ¾" thick requires 2"W X 6"L
  2. Bar or wire under ¼" diameter requires 18" long
  3. Pipe up to ¾" wall thickness requires 15" long; Pipe greater than ¾" wall thickness requires 6" long
  4. Requirement depends upon size and specification. We prefer ten inch length.
  5. 4"W X 6"L with longitudinal direction noted with 0.1" thickness

* Grain direction is very important when submitting sheet or plate for testing. Always mark grain direction with an arrow on the sample.
** When performing chemical analysis only, supply the above referenced size coupon. If other testing is to be performed (i.e. tensile, flattening, etc.), a separate piece for chemical analysis is not needed.

Wet Chemical Analysis

Metals - 5 grams minimum, 10 grams preferred
Aqueous Samples - 1/2 litre minimum, 1 litre preferred
Solid Particulate Samples - coarse (> 6mm) 1 kilogram minimum, medium (1 to 5 mm) 500 grams minimum, fines (< 1 mm) 100 grams minimum

Weld Procedure Qualification

The welded test plate should be a minimum of 10" wide by 12" along the weld, 16" along the weld if Charpy V-Notch impacts required.

Pipe qualifications:

  • Over 3" nominal diameter O.D. - 1 pipe
  • 2 - 3" nominal O.D. - 2 pipes
  • Less than 2" nominal pipe - 3 pipes
  • Charpy V-Notch impacts may require more material depending on pipe size and quantity of impact tests

Chemical, Micro and IGC ASTM A262 Practice E

  • Rod less than 10mm dia - 150mm long
  • Rod more than 10mm dia - 120mm long
  • Plate - 50mm X 100mm
  • Pipe - 100 mm long

Hydrogen-Induced Cracking (HIC) Test, NACE TM0284

To conduct the HIC test, TCR Advanced requires the following sample sizes:

If the plate is more than 80mm think - 250mm X 250 mm sample size is required
Pipe - upto 2" OD - 200mm long
If the pipe is more than 2" OD pipe - 100mm long sample size is required
Bars - Upto 3" dia - 300mm long
If the Bars are more than 3" dia to 5" dia - 200mm long sample size is required
If the Bars are more than 5" dia - 100mm long sample size is required
Number of pieces to be tested upto 88mm thick/dia - set of 3 pieces to be tested
Number of pieces to be tested more than 88mm thick/dia - 5 pieces to be tested
Time for completion - 2 weeks

Sulfide Stress Corrosion Cracking (SSCC), NACE TM0177

The SSCC tests at TCR Advanced in India are performed routinely for customers using tensile and bent beam specimens. For each stress level and temperature, the following sample size is required:
Plate - 25mm X 200mm with rolling direction marked on it
Pipe - 160mm long piece irrespective of dia
Bar - 160mm long piece irrespective of dia
